Abstract
The utility model relates to a water pump pressure controller. On a base with a joint, a pressure regulating device which is composed of a spring and a regulating screw presses a diaphragm onto a pressure sensing chamber of the base through a pressing block. The pressing block touches a rocking plate of an instantaneously changing device by the top. A movable contact piece is arranged on a spring plate of the instantaneously changing device, and a static contact piece is fixedly arranged in a static contact seat. A guide rod is fixed on the spring plate of the instantaneously changing device and movably penetrated in a guide hole of the static contact seat, and the movable contact plate is sheathed on the guide rod and is limited by steps on the guide rod. A pressing spring is arranged under the movable contact plate, and the cross sections of the guide rod and the guide hole are square figures corresponding to each other. When the controller is in working, under the action of the guide rod, the movable contact plate moves straightly, and no relative slip between the moving contact and the static contact exists. Thus, the possibility of creating electric arc can be decreased, and the electric life time is extended.
Description
Technical field
The utility model relates to the electrical automatic control equipment of pump, particularly to the improvement of the pressure controller of water pump.
Background technology
On electric water pump, for being reached on the set point at pressure, it quits work automatically in limited time, pressure drops under the set point in limited time and start automatically, to realize the purpose of control automatically, installed pressure controller on water pump.Present pressure controller, be on a base that has a joint, the regulator of being made up of spring and set screw is attached to pressing diaphragm on the pressure-sensitive chamber of this base by briquetting, briquetting contacts on the rocker of instantaneously changing device, movable contact spring is contained on the springboard of instantaneously changing device, and static contact is fixedly mounted in the breakback contact stand.Flange seat is connected on the pipeline, when pressure rises, surpasses certain value, and briquetting promotes the rocker of instantaneously changing device and crosses critical point, makes the rapid redirect of springboard of instantaneously changing device, movable contact spring action, the power supply of disconnection motor; On the contrary, when pressure dropped to certain value, the rocker of instantaneously changing device moved back critical point, also made the rapid redirect of springboard of instantaneously changing device, made the dynamic and static closing of contact, connected the power supply of motor, realized the automatic control of pump.
In the prior art, movable contact spring does not have guider, and slide relative easily takes place between the sound contact for the closing of contact or separately the time, causes electric arc to increase, and has shortened useful life.
Summary of the invention
The utility model purpose is to provide the pressure controller that has the water pump of guider on a kind of movable contact spring, to improve its electrical endurance.
Scheme of the present utility model is: a kind of water-aspirator pressure controller, having on the base of joint, the regulator of being made up of spring and set screw is attached to pressing diaphragm on the pressure-sensitive chamber of this base by briquetting, briquetting contacts on the rocker of instantaneously changing device, movable contact spring is contained on the springboard of instantaneously changing device, static contact is fixedly mounted in the breakback contact stand, be fixed with guide post on the springboard of instantaneously changing device, the guide post activity is located in the guide hole on the breakback contact stand, movable contact spring is enclosed within on the guide post, spacing by the step on the guide post, the below of movable contact spring is provided with stage clip.
The cross section of described guide post and the cross section of guide hole are in correspondence with each other square.
The utility model has the advantages that: because movable contact spring is enclosed within on the guide post, under its guide effect, during action, movable contact spring is a rectilinear motion, and sound does not have slide relative between the contact, can reduce the generation of electric arc, has prolonged electrical endurance.
Description of drawings
The utility model is described in further detail with embodiment with reference to the accompanying drawings below.
Accompanying drawing is a cross-sectional view of the present utility model.
Mark among the figure: 1 set screw, 2 springs, the rocker of 3 instantaneously changing devices, 4 briquettings, 5 diaphragms, 6 bases, the springboard of 7 instantaneously changing devices, 8 stage clips, 9 movable contact springs, 10 guide posts, 11 static contacts, 12 breakback contact stands.
Embodiment
As shown in the figure, the water-aspirator pressure controller of embodiment, be on the base 6 that has joint, the regulator of being made up of spring 2 and set screw 1 overlays diaphragm 5 on the pressure-sensitive chamber of base 6 by briquetting 4, briquetting 4 contacts on the rocker 3 of instantaneously changing device, movable contact spring 9 is contained on the springboard 7 of instantaneously changing device, and static contact 11 is fixedly mounted in the breakback contact stand 12, and above structure is identical with existing water-aspirator pressure controller.
In an embodiment, be fixed with guide post 10 on the springboard 7 of instantaneously changing device, guide post 10 activities are located in the guide hole on the breakback contact stand 12, can move up and down, movable contact spring 9 is enclosed within on the guide post 10, and is spacing by the step on the guide post 10, make that movable contact spring 9 can be below limited step among a small circle in move up and down, the below of movable contact spring 9 is provided with stage clip 8, with the contact pressure of assurance sound contact, and the reliable contact after the loss of contact.
The cross section of described guide post 10 and the cross section of guide hole are in correspondence with each other square, prevent that movable contact spring 9 from rotating.
During work, when pressure rises, surpass certain value, the rocker 3 that briquetting 4 promotes the instantaneously changing device is crossed critical point, makes the springboard 7 rapid redirects of instantaneously changing device, movable contact spring 9 actions, the power supply of disconnection motor; On the contrary, when pressure dropped to certain value, the rocker 3 of instantaneously changing device moved back critical point, also made the springboard 7 rapid redirects of instantaneously changing device, made the dynamic and static closing of contact, connected the power supply of motor, realized the automatic control of pump.
During action, movable contact spring 9 is a rectilinear motion, and sound does not have slide relative between the contact, can reduce the generation of electric arc, has prolonged electrical endurance.
